Product Details

The Powermaster 8-57141 is a high-performance alternator designed specifically for Ford applications requiring increased electrical output. This upgrade alternator delivers superior charging capacity compared to factory units, making it ideal for vehicles with high electrical demands from aftermarket accessories, audio systems, or performance modifications.

Key Features:

  • High-output design provides increased amperage over stock alternators
  • Direct bolt-in replacement for easy installation
  • Natural aluminum finish for corrosion resistance and heat dissipation
  • Premium quality construction with heavy-duty internal components
  • 100% new components—not remanufactured
  • Engineered to handle high-demand electrical systems
  • Includes mounting hardware and necessary components

Powermaster alternators are built to exacting standards using premium materials and precision manufacturing. This alternator is designed to maintain consistent voltage output even under heavy electrical loads, preventing dimming lights and voltage drops that can occur with undersized charging systems. The durable construction ensures reliable performance and extended service life in demanding automotive applications.

Good so far

I wish I could find the 30 series tire for the front of my mustang .. but I don't see that you sell them ?

Great!

I bought a tire for my truck,and now I'm ordering these wheel locks.I really find your site very easy to order from,and like your prices and turn around time

Everything was great, will use this site again!

I haven't received my parts yet, but they just notified me that the order has been shipped. I think this is very fast service. Their online ordering system was very easy to use. And best of all, they had the lowest prices on the items I ordered. Even the shipping charge was less than some other companies. So far, I am very satisfied with Autoplicity, and I will certainly check their Website the next time I'm looking for parts.

Autoplicity had an item my vendor had on backorder for weeks in stock and shipped it very quickly. I'm glad i found this place on the web, and will be looking forward to doing business with them in the future!

Best prices, fast shipping, and product as described. I would definitely recommend Autoplicity.

Great products. Super fast shipping,and best prices anywhere! Thx!!

I looked around for few months on where to go to purchase JBA headers for my 01 Tundra. I came across Autoplicity and their prices were untouchable. I even called to speak with a sales representative and he gave me a discount code for my purchase. I would highly recommend doing business and plan on doing more business with them.

Great transaction at a great price.

Fast, Professional and great prices.

Reasonable prices, item shipped quickly, easy to navigate site. Shipping prices were a bit high for my liking though.

GREAT PRICES FAST SHIPPING WILL UPDATE ONCE PRODUCT ARRIVES
